Patent Term Adjustments (PTA) and Extensions (PTE):

• Patent Term Adjustments (PTA): Patent Term Adjustment (PTA) can extend the term of a U.S. patent to compensate for delays caused by the USPTO during the patent's prosecution. These delays are associated with specific timelines the USPTO is required to meet, such as issuing a first office action within 14 months of filing, responding to applicant replies within four months, and issuing a patent within 36 months from the filing date. While the Google Patents record for US819866B2 indicates an "Adjusted expiration" date, it does not provide specific details on any PTA days granted.
• Patent Term Extensions (PTE): Patent Term Extensions (PTE) are available for patents claiming products (like human drugs, food additives, medical devices, etc.) that require regulatory approval, such as from the FDA. PTE aims to restore patent term lost during the regulatory review process. There is no information in the provided context to suggest that US patent 8,198,686, which relates to a semiconductor device, has received or is eligible for a PTE.
